Normalladingen tar lengre tid.

Because -en is the definite article attached to the noun.

• normallading = normal charging
• normalladingen = the normal charging / normal charging as a specific process

In Norwegian, you usually do not put a separate word for the in front of the noun the way you do in English. Instead, it is often added to the end of the noun.

It is a compound noun:

• normal = normal
• lading = charging
• normallading = normal charging
• normalladingen = the normal charging

Compound nouns are very common in Norwegian, and they are usually written as one word.

Norwegian often marks definiteness with an ending on the noun instead of a separate article.

So:

• en lading = a charging
• ladingen = the charging

That is why you get normalladingen, not something like den normallading in this sentence.

Tar is the present tense of å ta (to take).

• å ta = infinitive, to take
• tar = present tense, takes

So Normalladingen tar lengre tid literally follows the pattern:

The normal charging takes longer time

This is the normal form for a present-tense statement.

Ta tid is a very common expression meaning to take time.

Examples:

• Det tar tid. = It takes time.
• Ladingen tar tid. = The charging takes time.
• Normalladingen tar lengre tid. = Normal charging takes longer.

So here tar is not about physically taking something. It is part of the expression take time.

Lengre is the comparative form, meaning longer.

• lang = long
• lengre = longer

So:

• lang tid = a long time
• lengre tid = a longer time

In this sentence, it means the process takes more time than something else.

This is a very common learner question.

In careful Bokmål, a useful rule is:

• lengre is often used as a comparative adjective, especially before a noun
• lenger is often used more like an adverb

Since tid is a noun, lengre tid is the natural form here.

Compare:

• Det tar lengre tid. = It takes longer time.
• Det varer lenger. = It lasts longer.

In everyday speech, you may hear some overlap, but lengre tid is the standard form in this sentence.

Because Norwegian often uses tid without an article in expressions like this.

• Det tar tid. = It takes time.
• Det tar lang tid. = It takes a long time.
• Det tar lengre tid. = It takes longer.

Using en here would sound unnatural in this expression. Norwegian treats tid a bit like an uncountable idea in this kind of phrase.

Yes, you often can.

The difference is roughly:

• Normallading tar lengre tid. = Normal charging takes longer (more general)
• Normalladingen tar lengre tid. = The normal charging takes longer / a more specific charging mode or instance

So the version with -en sounds more definite or context-specific.

This sentence has the basic Norwegian main-clause order:

subject + verb + rest

• Normalladingen = subject
• tar = verb
• lengre tid = the rest of the predicate

So it is very straightforward.

A useful thing to remember is that Norwegian usually keeps the finite verb in second position in main clauses. For example:

• Normalladingen tar lengre tid.
• Om vinteren tar normalladingen lengre tid.

In the second sentence, Om vinteren comes first, so tar still stays in second position.

Yes, that is also possible, but the nuance is slightly different.

• tar mer tid = takes more time
• tar lengre tid = takes longer

Both can work, but tar lengre tid is especially natural when talking about the duration of a process. It focuses on the idea that the process lasts longer before it is finished.

Yes. This is a very natural Norwegian structure for talking about how long a process takes.

You will often see patterns like:

• Ladingen tar tid. = Charging takes time.
• Hurtiglading tar kortere tid. = Fast charging takes less time / is quicker.
• Normalladingen tar lengre tid. = Normal charging takes longer.

So this sentence uses very normal grammar and a very common expression.
